Hello,
If I have two transformers with output 100mA one at 12 and the other at the 24v, and connect them to parallel will I get 200mA and what will be voltage?

You would get 24V, and the 12V transformer would most likely suffer damage because the higher voltage transformer would force current through the lower voltage transformer.
You could connect them in series to get a 36V source, but don't do parallel!

With the 36 volt supply, you could then use a buck converter to step down the voltage whilst increasing the current capacity.

What if I connect AC TO DC rectifier to both transformers and then connect them to parallel?

Then you will have 24V, and the lower transformer+bridge rectifier will remain reverse biased and not contribute at all.
You cannot mix voltages when you are putting things in parallel. Ever. For sources or loads.
