Alpha and Omega
A cutoff of .70 is often used for reliabilities. McDonald’s Omega is a more general form of the Cronbach’s Alpha and more reliable (Hayes & Coutts, 2020). See the reference below for more information about the difference between these two.
IMPORTANT: to get correct reliabilities, you should reverse code items that are negatively framed.

AVE and SV
Looking at the Average Variance Extracted (AVE) and Shared Variance (SV) is another way to examine convergent and discriminant validity (Fornell & Larcker, 1981; Farell, 2010). The AVE is the average amount of variance that the latent construct is able to explain in the observed items. SV is the amount of variance that the latent factor shares with another latent factor.

ICC
If you have indicated that your data is clustered, ConMET also displays the ICCs (Bliese, 1998).  
These ICCs are calculated on estimated factor scores. You can also get the ICCs for an observed variable by putting them as a single-item factor in the model and then run the CFA.
