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.
