Which realms are you talking about? The 10 (6low/4high)buddhist ones, or the 6 ones (3low/3high)? It doesen't make a big difference, but it is still a starting point.
He said he sees you in the lower realms; as far as I know, those are the realms of defects of the human being. You might be aware of your own defects and have the desire to change, which is taking you to those realms. Which make me wonder about the psychic who is aware of the himan power and still travels in the lower realms, but again, I am not very experienced in reaching these realms.
Astral travel is usually done whole sleeping, when the mind can seprate itself from the physical body. The logic mind, usually can't let this happen while you are awake.
Stating before you fall asleep that you are going to travel astrally and remember everything, might help. Your subconscious can do a lot of things; it only has to be asked to do them.
And writing them down is a great idea. You can see patterns, and wrote about places that you will maybe get to see physically too. Such things can give you the certainty that you were actually astral travelling.

Which gemstones should I use and how to use in case I would like to contact my spirit guides, ascended masters and gain knowledge and experience regarding my past lives.
It depends on what you want to try first. You can't learn all of them at the same time. And gems are just aiding, you will also have to learn how to do these things. There are different technique for each andevery one of them, but you can adapt them in order to feel right to you. It may come naturally, or you will have to work for it, but it is possible.

Banish them. Burn sage, cast a protection spell, cast a circle on your entire house, ask good entities to protect you and maybe also wear a pentacle or a sumbol that is charged with protective energy.
Gemstones are helping too, but I don't use them much.
