Hello
...
You can see them on my page -

They look good.

I turned them a bit to thin, 10mm. Now they are a bit warped. Can I finish
turning them even if they are warped?

That all depends. if the warp is less than 10mm, you could try to make them
round again. But if the warp is too much you'd go through the side. The
pictures don't make them look too thin for starters. And since they have
cracks in them, they will never be perfect specimens of the turning art. I'd
leave them warped, makes them more interesting. And depending on the age of
the wood (now) they could move even more.

Do I shape bottom of a bowl with a gouge or with a chisel? I mean before
inserting it in chuck.

Save the bottom (outside) of the bowl for later, after you finish the inside.
then either use a Cole Jaw chuck, or make a jamb chuck. Then finish turn the
bottom with only a live-center to interfere with your work. Then what ever
tool is most comfortable - me, I'd use my 1/2" bowl gouge.

You can see that I used CA glue to fill the cracks - will I have to use it
again if I finish turning them?

If the CA glue hasn't filled the crack and you open a void again, yes.

You'll probably say why bother. But they are my first bowls, so I want to
keep them

By all means keep them. If they are not perfect they will become samples of
where you started, and you will see improvements in the next turnings you do.
If you make them Perfect then the only way to go is down. Think of the
"Fastest Gun In The West", he can't improve 'cause he is the best.
