Do these sentences sound natural?

The 2nd and 3rd sentences aren't correct. A frankly manner? An honestly manner?

And the use of slashes to separate words is not correct, except informally in certain situations, like the one below, when it can be used to mean 'or'.

I was received openly, frankly, honestly and with a warm heart (or in a warmhearted manner).
I was received in an open, frank, honest and warmhearted manner/way.
