Consider the following three sentences:
- If I had the money, I would get the operation.
- If only I had the money, I would get the operation.
- I would get the operation only if I had the money.
The first expresses a simple failed conditional. I don't have the money, but if I did, I would get the operation.
The second expresses a failed conditional with greater emotional content. I don't have the money, but if I did, I would get the operation and it really bothers me.
The third expresses a failed conditional, without the emotional content, but with a greater stress on the monetary constraint.
Well the biggest difference is aloud is an adverb, but loud is an adjective.
But there is likely some confusion between "Aloud", "Out loud","Loudly", which are all adverbs.
"Aloud" is an adverb used in contrast to saying or thinking something quietly. So usage might be
"She read her secret journal aloud to the class."
or
"He couldn't help but to weep aloud".
More importantly, you should know that "aloud" is generally deemed as formal, and is rarely used in conversation.
"Out Loud" is almost the same as "aloud", they can usually be used interchangeably. For example
"He couldn't help but to weep out loud"
or
"She read her secret journal out loud to the class."
The difference with out loud is that it can also be used to imply that it was a sudden or unexpected out burst.
So in the acronym "LOL" (laugh out loud), it is laughing audibly as opposed to what people normally do when they are reading on the internet, which is laughing in their head or very quietly.
"Out loud" is much more common than "aloud". I can't think of an instance where I would say "aloud" in conversation without sounding a bit awkward.
"Loudly" is used most often as a quantifier of something that's loud enough or too loud. Typically, it's in a negative context.
For example in a negative context:
She is playing her music way too loudly.
or
You are speaking too loudly in the library.
And in a positive context:
He spoke loudly so everyone could hear him.

Only the first sentence is correct.
The phrase is planned is passive voice - meaning that someone unmentioned has planned the meeting.
The phrase has planned is active voice - meaning that the subject of the sentence has actively done the planning. "The meeting has planned..." makes no sense because the meeting is not a person who is capable of doing the action of planning.
It might be clearer if we add in the person doing the planning. Call this person "Maurice". Adding Maurice to both of your sentences:
Note that in 1. I just had to insert the phrase "by Maurice" but in 2. I had to move around the words "the meeting" in order to make Maurice the subject of the sentence as the person actually doing the planning.
