I wake up every day at 6 AM.

And then I do work out 1 hfor an hour 6 times a week.

After finish my workout, I go to work at 8:30 AM.

My job is startI work from 9 AM to 5 PM.

You could also say "My job starts at 9 AM" or perhaps "My job goes from 9 AM to 5 PM," though the latter is a little less formal.

I wake up every day at 6 AM.

A few points:
1. Adjectives require nouns. In this case, you used the adjective "every" without a noun before or after. You have to put a noun, like "day", or "morning", otherwise you are not modifying anything. Adjectives usually modify nouns or pronouns (she, him, it, who, etc.)
For ex: "She is a slow runner" - the adjective "slow" is preceding the noun "runner" - you could not say "She is a slow", but because adjectives can modify pronouns, you could also say "She is slow" in response to a question about her running speed ("How fast of a runner is she?" "She is slow.")
2. You forgot to use the preposition "at" - you did use it in the sentence below, but you always use a preposition when referring to a time or place. Here is a good link you can use for more information: https://www.uvic.ca/learningandteaching/cac/assets/docs/Prepositions%20Final.pdf

And then I doI work out 1 hrfor 1 hour after breakfast 6 times a week.

You can start the sentence with "And" but I recommend starting it with the adverb itself. You can just use "afterwards" or "then" to better explain that, after eating breakfast, you do your workout. You did a similar thing with the sentence below, which was good.

However, I removed the adverb because we are talking about a habit that recurs often and is a usual part of your routine. Rather, I specified the time your workouts usually happen ("after breakfast).

I also removed the noun "workout" altogether and use the verb form ("work out") for better flow, though. You can do this with a number of sentences.
For example: "I do a dance class every Friday" could become "I dance every Friday". Or, "I take my car to work" becomes "I drive to work."

If you insist on using a noun, though, you need to use articles before nouns. This includes words like "a" and "the." Because you are not referring to a specific workout, you need to put "a" before the word "workout." And because "workout" is both an event and a noun, you should use a preposition ("for") when describing the duration ("1hr"). I would also recommend spelling out the word "hour."

The sentence would become "... I do a workout for 1 hour [on most days]..."

After finishing my workout, I go toleave for work at 8:30 AM.

Great usage of the adverb "After" to specify that, when your workout is done, you will do something else.

Make sure to use the correct format and tense of the verb "finish" here. You could say "After I finish" or "After finishing".

I would use the gerund here ("finishing"), as the workout is a continuous action with an unspecified stopping point. However, you can absolutely say "After I finish my workout, I leave for work..."

This link might help you understand the difference between using the gerund and the regular verb tense: https://ell.stackexchange.com/questions/193510/i-finish-vs-finishing

Finally, while "go to work" is not incorrect, I would say "leave" is clearer. You do not arrive at your workplace at 8:30, but rather you are leaving your gym or home to go to work at 8:30.

My job is startOn weekdays, I work from 9 AM to 5 PM.

The word "is" does not work here, grammatically. You should say "My job starts", or "I start work at" or something like that.

You also typically do not say "start from" when referring to a duration. You can say "start from" when referring to a place, such as "When cleaning the home, start from the entrance and work your way to the kitchen."

You would say "starting from" when referring to a duration that is somewhat unclear: "I have a ballet recital starting at 7pm."

With a duration that is known, you can say "starting at" or just "at" -- you can also use this for an unclear duration, too: "Ugh, I have a shift at 6AM tomorrow..." or "I'm not sure how long this party will be, but it starts at 9."

I also do not often see English speakers using the words "my job" to refer to a start and end time. Usually you would say "my job" when talking about specifics about your work, such as "My job pays me pretty well!" Rather, when talking about shifts or schedules, you would usually say "I work from X AM to Y PM"

I would also say that, because you specified how often you work out, you should specify when you work too. I included "On weekdays" for that purpose.

I wake up every 6 AMat 6 AM everyday.

Then, I eat breakfast at 7 AM.

And then I do workout 1 hfter breakfast, I workout for an hour 6 times aper week.

After I finish my workout, I go toleave for work at 8:30 AM.

My job is startwork schedule is from 9 AM to 5 PM.
