Is Google indexing my posts?

[Capz]

Hello everyone, good evening. I have an English blog page about recipes. It has been 1 month since I opened it, and I am posting 4-5 content per week. I am trying to understand some things as I have no coding knowledge. Through my online research, I am trying to learn some things. When I search on Google using the site:domain.com format, I noticed that one of my posts was indexed 3 times and another one 2 times. Most of my posts have not been indexed. It mentions redirection errors and I am having trouble figuring it out. Thank you in advance for your help.
