minecraft player.sendMessage command plugin not working

I'm new to coding and I am making a Minecraft command plugin for my mate, the plugin sends a message to the player when they use the command. I can't seem to get all of them working, only the first command will work on the server, I've tried everything I know like if-else, etc can someone help, please?

package com.legroom.applyplugin.Commands;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
public class commands implements CommandExecutor {
@Override
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
Player player = (Player) sender;
if (sender == null) {
}
if
(cmd.getName().equalsIgnoreCase("famous")) {
player.sendMessage("§7§m----------------------------");
player.sendMessage("§3» §3Requirements:");
player.sendMessage("§3» §f500+ Subscribers");
player.sendMessage("§3» §f1+ vid on the server");
player.sendMessage("§3» §fReasonable views/likes");
player.sendMessage("");
player.sendMessage("§3» To apply, use:");
player.sendMessage("§3    » §fMedia.nivina.cc");
player.sendMessage("");
player.sendMessage("§m----------------------------");
if
(cmd.getName().equalsIgnoreCase("appeal")) {
player.sendMessage("§7§m----------------------------");
player.sendMessage("");
player.sendMessage("§3» To appeal, use:");
player.sendMessage("§3     »§fDiscord.nivina.cc");
player.sendMessage("");
player.sendMessage("§7§m----------------------------");
if
(cmd.getName().equalsIgnoreCase("apply")) {
player.sendMessage("§7§m----------------------------");
player.sendMessage("");
player.sendMessage("§3» To apply, use:");
player.sendMessage("§3    » §fStaff.nivina.cc");
player.sendMessage("§3    » §fMedia.nivina.cc");
player.sendMessage("");
player.sendMessage("§7§m----------------------------");
if
(cmd.getName().equalsIgnoreCase("youtube")) {
player.sendMessage("§7§m----------------------------");
player.sendMessage("§3» §3Requirements:");
player.sendMessage("§3 » §f200+ Subscribers");
player.sendMessage("   » §f1+ vid on the server");
player.sendMessage("§3 » §fReasonable views/likes");
player.sendMessage("");
player.sendMessage("§3» To apply, use:");
player.sendMessage("§3» §fMedia.nivina.cc");
player.sendMessage("");
player.sendMessage("§m----------------------------");

return true;

You are nesting your if-statements:

if (condition) {
if (someOtherConditionThatConflictsWithFirstCondition) {
// Never reached
}
}

The second if-statement, because it is contained within the curly braces of the first, is only reached if the first condition evaluates to true. But your conditions are equals-operations on the same String, so if the first condition evaluates to true, the second cannot evaluate to true.

What you need to do instead is place them after one another:

if (condition) {
}
if (someOtherCondition) {
}
if (thirdCondition) {
}

Or alternatively:

if (condition) {
}
else if (someOtherCondition) {
}
else if (thirdCondition) {
}
