Well, I count 7 structural isomers........

Explanation:

And some of the isomers can support geometric isomerism.

"Cyclopropanes:"

"1,1,2-trimethylcyclopropane"

"1,2,3-trimethylcyclopropane"

"Cyclobutanes:"

"1,1-dimethylcyclobutane"

"1,2-dimethylcyclobutane"

"1,3-dimethylcyclobutane"

"Cyclopentanes:"

"methylcyclopentane"

"Cyclohexanes:"

"cyclohexane"

You should build some models to help you appreciate the geometric isomerism possible with cyclobutane series. "1,1,2-trimethylcyclopropane" can also (I think) support optical isomerism.
