Should I say dear god, dear Jesus, or dear lord when I begin to pray? And should I say in Jesus name amen when I end the prayer?

It's all good.

I start most of my prayers with " Oh Lord my God " and always end them in " in the name of Jesus I pray ".

Any way you start your prayer is good, God knows the thoughts and intents on the heart.

Yes, In Jesus name to end every prayer. No man goes to the Father but by that name Jesus.

I suggest beginning with "Dear Father in Heaven" and closing in the name of Jesus Christ.

Pray to GOD alone , since Jesus also pray to GOD, the Lord of all the worlds.

You can use any of them. I often pray starting with "Father", sometimes "Lord" and "Jesus". The prayer spoken (or unspoken) needs to be in faith and in sincerity. "A broken and a contrite heart, O God, thou wilt not despise".

One prayer formula taught by Jesus in the New Testament

- note that it is not the only prayer formula mentioned and certainly it is not required nor the only one approved

teaches that we are to pray to the Father in Jesus' name.

That is the way that I (almost) always pray.

If you knew Jesus, God would be your Father, and you wouldn’t have to ask this question.

Our Father who art in heaven if it's your will, pray, in the name of Jesus Christ....amen

and you don't have to say it out loud, He knows what you're thinking....

It's more powerful if you call on all 3 members of the Trinity. I would say "in the name of the Father, the Son, and the Holy Spirit"....then begin the prayer

You should say

Our Father in heaven,

Jehovah our Father

end the prayer

in Jesus name

God and Lord are titles which could mean anyone

God sees the intention of the heart the exact form of the prayer is not so essential

.

Pray as you are most comfortable. Imagine a wise older respected person in the room and speak to Jesus as you would to them.

Prayer comes from how you live your whole life - you need to work on becoming holy as well as practising prayer
