So rule for なってくる is the same as なる? But for na-adjective, there are no stem. So shouldn't it be
ひまになってくる ?
I am just a beginner. I guess ひまではあるんです and ひまではあります means "there is free time" but
ひまです means "I am free". Please correct and explain the meaning if I am wrong.

Yes, since the -tai form performs as an i-adjective, as same as the negative form as I pointed out previously. This rule is applied to all grammatical structures.
e.g.
高い --> 高くなる
行きたい --> 行きたくなる
行かない --> 行かなくなる
