It is true that God's name appears hundred of times in the Book of Psalms, I would like to add two of my favorites, from the New World Translation:
"May people know that you, whose name is Jehovah,
you alone are the Most High over all the earth."
Psalm 83:18
"Know that Jehovah is God. He is the one who made us,
and we belong to him."
Psalm 100:3
Hundreds of them, beginning with Psalm 1:2 (in the Hebrew).
"Psalm 151" is not included in the typical Protestant Bible, but it's found in some Eastern Orthodox and Catholic versions. In the context of a verse reference, it would be "Psalm 151:6." This specific verse would not be present in the book since the traditional Book of Psalms only includes up to 150 chapters.
It depends on context. If you are talking about Psalm 124, you would say "Psalm 124" since it is the name of that particular poem. If you wish to reference the specific verse Psalms 124:18, then you would say "Psalms" since that is the name of the book.
The book before Proverbs in the Bible is the Book of Psalms.

Psalms is also known as the Psalter. In Rabbinical literature, it is referred to as the Tehillim.
The longest book in the Bible is the book of Psalms with 150 chapters.

You can check The Bible book name, its chapter, and verse number if we have the verse. It is easier to look it up if you have either the verse topic or the verse itself.
There are 5 books (or sections) of Psalms. Each section of the book of Psalms corresponds to the first five books of the Old Testament, The Pentateuch.Book 1: Psalms 1-41Book 2: Psalms 42-72Book 3: Psalms 73-89Book 4: Psalms 90-106Book 5: Psalms 107-150
Maybe you're asking about the Tehillim. That is the Hebrew name of the Book of Psalms.
The book of Psalms credits King David as authoring about half of the book of Psalms, other authors credited in the book are Moses, Solomon, Herman, Ethan, the sons of Korah, and the sons of Asaph. About a third of the psalms have no author's name prefixed to them. They all were complied together in to the book of Psalm by an unknown priest or rabbi at a later time.
