Today iwas a wonderful day because of I can get up from bed until I wake up at 9amI was able to get out of bed and wake up by 9 a.m. in the morning.

The phrase "Today is a wonderful day" is in the present tense, but the rest of the paragraph is in past tense. To keep consistency, change "is" to "was."
"because of I can get up from bed until I wake up at 9 am in the morning": The phrase "because of" is incorrect here. Also, "I can get up" should be in the past tense, so it should be "I was able to get out of bed." "Until I wake up" doesn't make sense in this context; "wake up by 9 a.m." works better.

The sunlight was very hotstrong, and many people laidy on the grass ground.

"Hot" isn't the best word for sunlight (it’s usually "strong" or "bright"), and "laid" should be "lay" (past tense of "lie").
The word "ground" isn’t needed after "grass," so it’s cleaner to say "on the grass."

After sunthe sun went down, the weather became cold, and the wind gustpicked up.

"Sun down" should be "the sun went down," and "wind gust" should be "the wind picked up" or "there were gusts of wind."
"After the sun went down, the weather became cold, and the wind picked up."

We walked for a long time trying to find a dessert shop.

This sentence is grammatically correct, but it could be smoother in past tense by saying "trying to find" to show ongoing effort.

Maybe it was too late, as many shops were closed, and we haved to gottake the bus back to home.

The phrase "Maybe too late" needs to be changed to "Maybe it was too late" to match the past tense. "Many shop" should be "many shops" to make it plural. "We have to got" should be corrected to "we had to take" because it’s a past event. Finally, "back to home" should be simplified to "back home" to avoid redundancy.
