How many glasses of beers have you had? How many glasses of beer have you had?

I wasn’t entirely sure with this so I searched it up and you would, if using proper grammar, say something like what I’ve included above. However, in spoken English it is often shortened to your original sentence, which technically doesn’t use proper grammar since beer is an uncountable noun. This same concept applies to other drinks like coffee.

He always gets good results with less efforts. He always gets good results with less effort.

With the “he always gets good results” part, my best explanation would go as follows: You would first form a sentence as “he gets good results”, with he as the subject and gets as the verb. To add detail, you would add in always, as you did above. However always is an adverb (which always stays in this form), which means it doesn’t impact the conjugation of “get(s)”, and so it still ends with an S (gets).

He always get good results with lessminimal efforts. He always get good results with minimal effort.

less doesn't really make sense here, minimal/no/little would be better words to use.

He always get good results with less efforts. He always get good results with less effort.

effort is not countable so is not plural.

He always gets good results with lessittle efforts. He always gets good results with little effort.

He always get good results with less efforts. He always get good results with less effort.

few is for countable things of small numbers. If there is a little milk you could say there is some milk. If there are multiple bottles you could say "there are a few bottles of milk in the fridge"

There is fewsome milk in the fridge. There is some milk in the fridge.

There is fewa little milk in the fridge. There is a little milk in the fridge.

Shall I buy some beers? Shall I buy some beer?

In proper English grammar, beer always remains as beer. Also, “some” isn’t really followed by plurals, so you would typically say something like “a few” instead of some when using a plural afterwards.

It i's Ok. It's Ok.

the separate "It is" rather than the contraction "It's" sounds odd here. I think because OK is informal and "It is" sounds quite formal

There isare a few in the fridge. There are a few in the fridge.

“A few” indicates that you are referring to a plural word, or that there is more than one of the thing you are referring to. Since it refers to a plural, you would use “are” instead of “is”

There isare a few in the fridge. There are a few in the fridge.

a few = multiple of something

There isare a few in the fridge. There are a few in the fridge.

"is" is for singular so 1 beer but "a few" is plural so more than 1.
