I am doing a experimental study and multi-group analysis, is it possible that we can use different sample size in two different groups?

Yes, but you may loss power.

Note also that in some settings, like multiway ANOVA, samples with different size lay lead to quite hard to interpret results if you do not have a strong statistical background.
